Not that we want to make your Sony Ericsson Xperia arc feel obsolete, but Sony Ericsson says that their just announced Xperia arc S is 20% faster at rendering web pages and has 25% faster camera start times and media conversion times. The Sony Ericsson Xperia arc S has a 1.4GHz CPU, and it's a Qualcomm Snapdragon MSM8255 single core CPU. Sorry, no dual core here.
